課堂精講02一、基數詞的表達和用法1.基數詞的表達(1)表示數目多少的數詞叫基數詞，基數詞后面通常接可數名詞。基數詞(幾)one，two，three，four，five，six，seven，eight，nine基數詞(十幾)eleven，twelve，thirteen，fourteen，fifteen，sixteen，seventeen，eighteen，nineteen基數詞(幾十)ten，twenty，thirty，forty，fifty，sixty，seventy，eighty，ninety

(2)13—19的基數詞以teen結尾，20—90的整十位均以ty結尾。十位數與個位數之間要加連字符“-”，如：thirty-one31；百位和十位之間加and，如：onehundredandfifty150。2.基數詞的用法(1)“基數詞＋單數名詞＋形容詞”構成合成形容詞，如：afive-year-oldboy一個五歲的男孩，an800-metre-longbridge一座800米長的橋atwo-hourride=twohours’ride兩小時的車程(2)當hundred，thousand，million這些詞前面有具體的基數詞(如one，two，three...或several，afew等)時，需用單數形式，直接修飾名詞，不與of連用，強調“確切的數目”，如：twothousandpeople兩千人，threehundredmetres三百米。當表示“成百上千、成千上萬、數百萬”

等不確切的“大量、許多”

時，需用復數形式(hundreds，thousands，millions)，且必須與of連用，修飾可數名詞復數，如：hundredsofpeople數百人，thousandsofbirds成千上萬的鳥。二、序數詞的表達和用法1.序數詞的構成和表達(1)表示順序的數詞叫序數詞，序數詞的構成：①序數詞一般是以與之相應的基數詞詞尾加-th構成，如：fourth，tenth。但以下這些基數詞變為序數詞時，有特別之處。如：one—first，two—second，three—third，five—fifth，nine—ninth，twelve—twelfth。②以ty結尾的單詞，要先變y為i，再加-eth。如：thirty—thirtieth，fifty—fiftieth。③以one，two，three等結尾的多位數詞，只將個位數變成序數詞。如：twenty-one—twenty-first。(2)基數詞與序數詞對應的變化：基數詞序數詞基數詞序數詞onefirstthirtythirtiethtwosecondfortyfortieththreethirdfiftyfiftiethfivefifthsixtysixtietheighteighthseventyseventiethninenintheightyeightiethtwelvetwelfthninetyninetiethtwentytwentiethninety-oneninety-first

2.序數詞的用法(1)序數詞前面一般加定冠詞the或物主代詞等限定詞。如：thefirsttime第一次，hissecondson他的第二個兒子。(2)如果序數詞前加不定冠詞a/an，則表示“又一，再一”。如：I’vetriedtwice.AndIwantathirdtry.我已經試過兩次了，還想再試一次。(3)“the＋序數詞＋最高級＋名詞＋in/of＋比較范圍”的表達。如：TheYangtzeRiveristhefirstlongestriverinChina.長江是中國的第一長河。三、分數、小數、百分數的表達1.分數的表達：分子用基數詞，分母用序數詞，分子是1，分母用單數，分子大于1，分母用復數。當分母是2時，可用half；當分母是4時，可用quarter。如：onethird1/3，twothirds2/3，ahalf1/2，onefourth或aquarter1/4，threefourths或threequarters3/4。2.分數作主語時，謂語動詞要根據分數后的名詞來確定，如果是不可數名詞或是可數名詞單數則謂語動詞用單數，如果是可數名詞復數則謂語動詞用復數。如：ThreequartersoftheinformationcomesfromtheInternet.四分之三的信息來自互聯網。Halfoftheapplehasbeeneaten.這個蘋果的一半已被吃掉了。Onethirdofthestudentsherearefromruralareas.這里的學生有三分之一來自農村地區。3.小數和百分數的表達法(1)小數點讀作point，小數點前后的數用基數詞表示。如：zeropointzerofour0.04。(2)百分數用percent表示。如：threepercent3%。四、時間的表達1.時刻的表達：小時、點鐘、分鐘、秒鐘要用基數詞。表達方式時間讀法示例順讀法整點基數詞(＋o’clock)9：00
